 My steps 2 and 3 basically coincide with Steve's alternative solution. 1. Basic techniques to UP = 29.2. (6)h3 = (6-4)h8 = (4-8)f8 = (8)a8 - (8=476)a149 => c3, g1 <> 63. (1=6)f4 - (6)c6 = (6-1)c7 = (1)g7 => g6 <> 1 ; UP = 33 (Steve: yes, I consider this More... 09/Jun/10 1:35 AM |  |
 Similar to rwm's, just for step 2 I used kraken cell:2)Kraken cell (478)a4,=>g1<>3(4)a4-(4=6)a1||(7)a4-(7=8)a9-a8=(8-4)f8=(4-6)h8=(6)h3||(8)a4-a8=(8 -4)f8=(4-6)h8=(6)h3 09/Jun/10 2:23 AM |  |

 54:56 to you all from Portland, Oregon. Took me a while, but this worked (forgive me, but I am still learning the notation):UP 29.messy chain implies c3<>6then another long chain =>h5<>3,7. UP 33.coloring => a8<>6, UP 81 09/Jun/10 4:09 AM |  |
 ...with Steve's observation about rwm's step 3, I was able to contrive a simple 3 step solution to yesterday's puzzle (no Kraken set or AAIC). 09/Jun/10 4:15 AM |  |
 no need to nuke this one with Kraken sets! 09/Jun/10 5:17 AM |  |
 For all interested, I have posted a solution to the Apr 10 2010 tough, a real monster involving several Almost AIC's. It does have a complex and interesting step (number 04) involving an "almost" continuous loop. Any comments on this, including proper terminology, or a better presentation of the logic, are welcome. 09/Jun/10 5:18 AM |  |
 Looks like a nice time! 09/Jun/10 7:47 AM |  |
 rwm: the whole concept of an 'almost continuous loop' boggles my mind - I will carefully ponder your step 4 and then reserve an appointment with my therapist! 09/Jun/10 9:53 AM |  |
